Ba credited his performance to the three interchangeable attacking midfielders behind him.
"They make football look easy," the 27-year-old said. "I just try to run in behind and create space as well for them. I know when they have some space they will be dangerous.
"When you have players that understand football perfectly you just have to run and the ball comes in to your feet, so that’s what I’ll do. They create good space, make good passes, are intelligent in their game, so they make it easier."
